In Mark Wilkins' answer to Counter not giving the expected result, he has some code that looks like this:

   if (i == var4)
        cout << "\n Armstrong number " << counter << ": " << var4;


i++ is not formatted as code, despite having the same indentation as the line directly above it (which is).

Screenshot for effect

Why is this so?

The spaces looked identical but were not. It must be indented with plain spaces, no crazy unicode or tabs.

  • Nice spot, thanks! 20c2 a020 c2a0 20c2 a020 692b 2b3b 0a .. .. .. i++;.

    Funny thing is, using Chrome on Mac, sometimes my spacebar will insert a no-breaking space too... Perhaps I accidentally hit a modifier key somewhere. Feb 27, 2013 at 22:41

    It happens to me too, but I don't recall hitting any modifier.

  • Tabs actually work just fine.

  • This happened to me once too -- and it was also with Chrome on the Mac. Feb 28, 2013 at 5:20
  • Nick, note that someone else reported "in Chrome on Windows 7 Pro, I copied a block of code already in the site and pasted it just below the block that I copied - doubling the size of the block". @Ernest, do you happen to remember if it was a copy & paste action for you too? And please see balpha's answer here if it ever happens again...

  • @Arjan -- I believe it was indeed copy/paste, not from within the site, but from some other app into Chrome. Mar 6, 2013 at 2:43
